Struct DependencyInfo

pub struct DependencyInfo<'a> {
    pub dependency_flags: DependencyFlags,
    pub memory_barriers: &'a [MemoryBarrier<'a>],
    pub buffer_memory_barriers: &'a [BufferMemoryBarrier<'a>],
    pub image_memory_barriers: &'a [ImageMemoryBarrier<'a>],
    pub _ne: NonExhaustive<'a>,
}

Dependency info for barriers in a pipeline barrier command.

A pipeline barrier creates a dependency between commands submitted before the barrier (the source scope) and commands submitted after it (the destination scope). Each DependencyInfo consists of multiple individual barriers that concern either a single resource or operate globally.

Each barrier has a set of source/destination pipeline stages and source/destination memory access types. The pipeline stages create an execution dependency: the src_stages of commands submitted before the barrier must be completely finished before any of the dst_stages of commands after the barrier are allowed to start. The memory access types create a memory dependency: in addition to the execution dependency, any src_access performed before the barrier must be made available and visible before any dst_access are made after the barrier.

Fields

dependency_flags: DependencyFlags

Flags to modify how the execution and memory dependencies are formed.

The default value is empty.

memory_barriers: &'a [MemoryBarrier<'a>]

Memory barriers for global operations and accesses, not limited to a single resource.

The default value is empty.

buffer_memory_barriers: &'a [BufferMemoryBarrier<'a>]

Memory barriers for individual buffers.

The default value is empty.

image_memory_barriers: &'a [ImageMemoryBarrier<'a>]

Memory barriers for individual images.

The default value is empty.

_ne: NonExhaustive<'a>

Implementations

impl DependencyInfo<'_>

pub fn is_empty(&self) -> bool

Returns true if self doesn’t contain any barriers.

Trait Implementations

impl<'a> Clone for DependencyInfo<'a>

fn clone(&self) -> DependencyInfo<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for DependencyInfo<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DependencyInfo<'_>

fn default() -> Self

Returns the “default value” for a type.
